Pagination problem with many users-Simple Certificate Bulk Operations No Display

[gumiho1593]

we've been using Simple Certificate module in Moodle since July 2014, the number of enrolled in one of our course is now 2,000+ , since yesterday we encounter a problem with regards to Bulk Operations tab.. the student list can't be displayed.. while I try on other courses with less enrolled students it still works.. is there a max limit for simplecertificate to issue certs? The image below is the only displayed once I click on the bulk operations.. kindly help me with this.. thanks in advance..

i really don't know, never test it with many users, try in plugin's forums if someone has this issue.
Try to turn on the debug mode.

thanks for reminding to turn on the debug mode :D we've changed the memory_limit of our server and hopefully it works! :)

Try to change pagination code, only get page data, not full list and break then
